ATTACHMENT FOR PAPER J'OGGERS.

Application filed` July 16, 1924. Serial No. 726,372.

To all 'whom it may concern:

Be it known that I, WALTER A. MCGARVIN, a citizen of the United States,and a resident of Los Angeles, in the'county of Los An'- v s geles andState of California, have invented certain new and useful Improvementsin Attachments for Paper Joggers, of which the following is aspecification.

My invention relates to paper joggers for 1o printing presses, and inpaper joggers as heretofore proposed the stock guides which are designedto jog the sheets of paper into alined position for stacking have beenfound to fail in their purpose because of the fact that they, beingrigid and unyielding, the

jogging action is too severe, with the result that the sheets, insteadof being alined, are bent or.folded at their edges and thus remain indisalined positions.

It is a purpose of my invention to provide a simple and inexpensiveattachment for the conventional jogger by means of which the jogging ofthe paper sheets into alined position is positively insured.

It is also a purpose of my invention to provide an attachment for paperjoggers which includes elements for properly guiding the sheets of paperinto the j ogger as received from the press.

,I will describe only one form of attachment for paper joggers embodyingmy invention, and one form of conventional paper jogger, and will thenpoint out the novel features thereof in claims.

In the accompanying drawings Figure 1 is a vertical sectional view takenon the line 1-1 of Figure 8, showing a paper jogger having appliedthereto one form of attachment embodying my invenl 4o tion; Figure 2 isa top plan view of the jogger and the attachment shown in Figure 1;

Figure 3 is a view showing in endelevation the jogger and theattachment;

Figure 4 is a detail perspective view` of one of the side stock guidesshown in the preceding views, and with the attachment embodying myinvention applied thereto; Figure 5 isla "etail perspective view of theend stock guide shown in the preceding views, and having applied theretoanother i attachment embodying my invention.

Similar reference vcharacters refer to similar parts in each of theseveral views of the drawing.

Referring specifically to the drawings, the conventional paper jogger ishere shown as comprising a receiving table T to which the papersheetsfrom a printing press are suco'essively delivered by means of feedingtapes F continuously movable over rollers R. The paper sheets areadapted to be stacked in vertical alinement upon the table T and as thesheets accumulate thereon the table moves step by step downwardly toaccommodate the sheets, as will be understood, Above the table are threestock guides G, G and G2, which are adapted to be continuouslyreciprocated transversely for jogging the sheets as delivered to thetable into vertically alined position.

The guide G2 consists of a supporting` formed with slots 19 to receivescrew bolts` 20 by means of which an adjustment of the plates 18 withrespect to the plate 15- will be effected for the purpose of increasingor decreasing the lengtlil of' the guide. As shownin Figurev 3, theplates 18 are formed withperforations 2lv through which guide Wires 22are adapted to extend for the purpose of preventing the paper sheets asdelivered from the press from flying upwardly. As shownvin Figure 1, thewires are curved rearwardly and upwardly and formed with hooked ends 22awhich engage a rod 23 disposed above the feeding tapes F. The rod 16 isadapted to be reciprocated through a crank connection 23 with a shaft24, the latter being oscillated by suitable mechanism. The rod 16 isprovided with a yV-shaped cam 25 having engagement" with rollers 26fixed on the ends of rods 27 normally urged in the direction of the camby springs 28. -Adjustably lixed to the rods by means of clamps 29 arethe guides G and G', and these guides in the present instance consist ofplates 30 which are 'disposed at tion 31 serves to connect the attachingportion with the active' portion, and as the entire plate 31 is formedof resilient material it will be clear that the active portion 31b isyieldingly supported upon the plate 30. As shown in Figure 4 theattaching -portion 31 is extended rearwardly beyond the plate and curvedoutwardly to provide a guide plate 3ld which extends between and abovethe rollers R, as clearly shown in Figure 1. The two guide plates 31aco-operate to guide the paper sheetsas delivered from the feeding tapesinto proper position upon the receiving table T.

The stock guide G2 is provided with members similar to the plates 31,but because of the construction of the guide member, as previouslydescribed, the members are in the form of tWo strips 32 of resilientmaterial, and each strip comprising an attaching portion 32a, an activeportion 32b and a connecting portion 32. These strips 32 are secured tothe plates 18 and are designed -to function in the same manner as theplates 31.

In the operation of the jogger the stock guides in their reciprocatingmovement normally operate to jog the paper sheets upon the table T andinto vertically alined posi-I tion, the confronting sides of the joggershaving contact with the edges of the sheets in moving the latter intoalined position. With the attachment in applied position to the guidesthey are interposed between the guides and the paper sheets so that asthe guides move toward the'sheets, the active portions 31b and B2bcontact with the edges of the sheets and under the movement of theguides jog the sheets into vertically alined position. By virtue of thefact that,

the active portions 31b and'32b are yieldingly supported it will beclear that during movement of the uides they yield under the pressureexerted by the guides so-as to graduate the jogging action of the guidesand thus prevent bending or folding of the edges of the paper sheets,while at the same time moving the sheets into vertically alined paperjoggers embodying my invention, it

is to be understood that various changes and modifications may be madeherein without departing from Athe/spirit of the invention and thespirit and scope oi the appended claims.

I claim:

1. In combination, a paper jogger having stock guides, means foractuating the guides, and yieldable means adapted to be interposedbetween the vguides and sheets of paper to be jogged for graduating thejogging action of the guides whereby jogging of the papersheets intoalined position is insured.

2. In combination, a stock guide, and a resilient member on [the lactiveside of the guide, said member being adapted to yield when the guide isvmoved toward the paper sheet to be jogged to graduate the jogging actionof the guide,for the purpose described.

3. An attachment for stock guides comprising a member of yieldablematerial connected thereto, and operable to graduate the jogging actionof said guides.

4. An attachment for stock guides comprising a stri of resilientmaterial adapted to be vibrate for graduating the jogging action of theguides.

5. An attachment for stock guides comprising a member of resilientmaterial having an attaching portion adapted to be secured contiguous tothe guide, and an active portion offset with respect tothe attachingportion and spaced from the guide.

6. An attachment for stock guides comprising a member oresilientmaterial h aving an attaching portion adapted to be secured contiguousto the guide, an active portion oliset With respect to the attachingportion and spaced from the guide, and a guiding extension projectingfrom onel end of the member or the purpose described.

7. An attachment for stock guides comprising a member of resilientmaterial having an attaching portion adapted to besecured contiguous tothe guide, an active portion offset with respect to the attachingportion and spaced from the guide, and a guiding-extension projectingfrom one end vof the member and curved outwardly.

8. In combination,v apaper jogger comprising a pair of guides spacedapart and a third guide between and at rightl angles to the firstguides, and resilient members on the confronting sides of the ,guidesfor the purpose described.

9. In combination, a paper jogger comprising a pair of guides spacedapart and a third guide between and at right angles to the irstvguides,a resilient member on each of the first guides, and a plurality ofresilient members on the third guide.

10. In combination,` a paper jogger com-4 lthe character describedcomprising a sheet of resilient material having vertically offsetportions, and a curved extension onone of the portions.

12. An attachment for stock guides comprising a resilient member adaptedfor vibration in unison with the jogging action of the guides.

13. In combination, a paper jogger and stock guide, and means on saldguide adapted for vibration resultant of the jogging movement of saidguides, for jogging the paper sheets into alined position.

14. In combination, a paper jogger having stock guides and means adaptedfor vibration by the actuation of said guides for jogging the papersheets into alined position.
